One of the nice things about working for Pivotal is that they have a great agile development division called Pivotal Labs.

The teams within Labs are big proponents of Lean and XP software methodologies such as pair programming and test-driven development. Their love of testing has had a particular impact on Spring Boot 1.4 as we’ve started to get great feedback on things that could be improved. This blog post highlights some of the new testing features that have just landed in the latest M2 release. Testing Without Spring The easiest way to unit test any Spring @Component is to not involve Spring at all! Structure your code with clean separation of concerns so that individual parts can be unit tested.

With Spring Framework 4.3 it’s very easy to write components that use constructor injections as you no longer need to use @Autowired. Testing MyComponent is now as simple as directly creating it, and calling some methods:
Spring Boot. Upload Scott Work Loading...

Working... ► Play all. Brians Java Blog: Spring Boot, Angular & Amazon Web Services. In order to access protected resources using Amazons SDK an access key and a secret key must be supplied.

Spring Cloud for AWS provides an XML namespace for configuring both values so that they are available to the SDK at runtime. Line 14 sets the access key and secret key required by the SDK. It's important to note that these values should not be set directly in your configuration or properties files and should be passed to the application on start up (via environment or system variables). The secret key as the name suggests is very sensitive and if compromised will provide a user with access to all AWS services on your account.
Spring Boot and Database initialization. Spring boot is hands down a great framework, saving the developer a lot of time and energy when developing a spring application.

One of its great features is database initialization. You can use spring boot in order to initialize your sql database.
Spring Boot REST Example. In this article we will build a REST application using Spring Boot.

Spring Boot aims at simplifying Spring application bootstrapping by providing a set of starter project templates. The project templates help add the necessary dependencies.
Build a new Web Application from scratch using Spring boot, Thymeleaf, AngularJS ? Part 2. In this series of blogs we are building a complete web app using Springboot,Angular, etc.

In the last blog, we made a basic landing page with Thymeleaf. In this blog we will introduce bower, which is used to manage front end dependencies like CSS,JS. 1.) Bower Install bower using this link. After bower is installed, we need to configure it to use in our app.
Spring Boot 101 (Part 4) - Thymeleaf. Spring Boot 101 (Part 2) - REST Controllers. Event Sourcing in Microservices Using Spring Cloud and Reactor. While the backing services in the middle layer are still considered to be microservices, they solve a set of concerns that are purely operational and security-related.

The business logic of this application sits almost entirely in our bottom layer. These applications are designed around business capabilities of the fictitious online store, which I’ve gone ahead and branded as Cloud Native Outfitters–a hypothetical Silicon Valley startup that sells 4 really clever t-shirts and hoodies. As a part of the business capabilities of the online store, we have the following 5 microservices that will serve as our backend REST API.

The main consumer of these APIs is the Online Store Web, as well as other planned customer facing applications that may never see the light of day in the case that Cloud Native Outfitters is unable to secure a seed round of investment from one of the top-tier venture capital firms on Sand Hill Road. These applications can be found at:
Angularjs and Spring Integration Tutorial. HTML5, rich browser-based features, and the single page application are extremely valuable tools for modern development.

Every application requires a server side (backend) framework besides the client side (frontend) framework. The server side can serve content, render dynamic HTML, authenticate users, secure access to protect resources or interact with Javascript in the browser through HTTP and JSON. Spring has been always one of the popular server sides framework in java world. On the other hand, Angularjs becomes popular for the single page applications in the client side. In this tutorial, we show how this two framework integrate easily and works together. AngularJS Programming Cookbook In this ebook, we provide a compilation of AngularJS based examples that will help you kick-start your own web projects.

Spring Boot for DevOps. Using the H2 Database Console in Spring Boot with Spring Security - DZone Database. Frequently when developing Spring based applications, you will use the H2 in memory database during your development process.

Its light, fast, and easy to use. It generally does a great job of emulating other RDBMs which you see more frequently for production use (ie, Oracle, MySQL, Postgres). When developing Spring Applications, its common to use JPA/Hibernate and leverage Hibernate’s schema generation capabilities. With H2, your database is created by Hibernate every time you start the application. Thus, the database is brought up in a known and consistent state. H2 ships with a web based database console, which you can use while your application is under development.
GitHub - mybatis/spring-boot-starter: MyBatis integration with Spring Boot. Bootstrapping Your Microservices Architecture with JHipster and Spring. Julien Dubois is the lead developer of JHipster, a Yeoman generator for Spring and AngularJS applications.

Julien’s here to show how you can use a generator like JHipster to address some of the design concerns microservices introduce like discovery and routing so you can focus on your core business logic. What is JHipster? JHipster (for Java Hipster) is an Open Source application generator, based on Yeoman. It generates a Spring Boot (that's the Java part) and AngularJS (that's the hipster part) application, with tooling and configuration all set up for you. In this post, you’ll learn how you can use JHipster to generate a microservices stack to address design concerns like service registration, configuration and client side routing.

With more than 200 contributors and 200,000 downloads, JHipster is currently the most popular Java application generator, and it has reached its 3.0 version last month, focusing on microservices using the Spring Cloud Netflix stack. yo jhipster . Going further. Real-time Applications with AngularJS and Java – Part 3. 1. Introduction This article is the last one of a series of three on real-time applications. In part 1, I have created a simple Task management application and implemented the Periodic Refresh AJAX pattern to make it feel as if the UI was updated in real-time when tasks were created. In part 2, I modified the project so only updated (delta) information was sent to the browser and I implemented Long Polling to get a better real-time feel. The plan now in part 3 is to go ahead and try the HTML5 WebSocket. This example was built using Maven, Spring, Jackson, Gson and Tomcat 8 (JDK8) for the back-end and AngularJS, Bootstrap, HTML5 and Bower for the front-end.

Trying out Spring Boot 1.4.0 new features and enhancements – Zoltan Altfatter – Software Engineer. In this post I am looking into Spring Boot 1.4.0-M2 version trying out the new features and enhancements. Spring Boot 1.4.0-M2 upgrades to Spring 4.3.0-RC1 and Hibernate 5.1. In Spring 4.3.0-RC1 there are lots of new features and enhancements. The full list you can find it here. Some of my favourites are The introduction of composed annotations from @RequestMapping like for example @GetMapping as a shortcut for @RequestMapping(method = RequestMethod.GET) @RestControllerclass ChuckNorrisFactController { @GetMapping("/") public ChuckNorrisFact getOneRandomly() { return service.getOneRandomly(); }} No need to specify @Autowired for constructor injection if the target bean defines only one constructor which is mostly the case. The general upgrade instruction from the Hibernate team can be found here.

Spring Cloud Series - Microservices using Spring Boot, Jersey, Swagger and Docker. Having used Spring for some years, I was impressed how easy it is to develop Spring-based apps using Spring Boot, an opinionated framework favoring convention over configuration and more impressed how easy it is to build and use common components of distributed systems using Spring Cloud which is built on top of Spring Boot.

This is the first of a few entries Spring Cloud Series covers on this blog.
Xavier Padró's Blog: Data aggregation with Spring Data MongoDB and Spring Boot. MongoDB aggregation framework is designed for grouping documents and transforming them into an aggregated result. The aggregation query consists in defining several stages that will be executed in a pipeline. If you are interested in more in-depth details about the framework, then mongodb docs are a good point to start. The point of this post is to write a web application for querying mongodb in order to get aggregated results from the database. We will do it in a very easy way thanks to Spring Boot and Spring Data. Actually it is really fast to implement the application, since Spring Boot will take care of all the necessary setup and Spring Data will help us configure the repositories.

Building REST APIs With Spring Boot. How SpringBoot AutoConfiguration magic works? - SivaLabs. In my previous post Why SpringBoot? We have looked at how to create a SpringBoot application. But you may or may not understand what is going on behind the scenes. You may want to understand the magic behind the SpringBoot’s AutoConfiguration. But before that you should know about Spring’s @Conditional feature based on which all the SpringBoot’s AutoConfiguration magic depends. Exploring the power of @Conditional While developing Spring based applications we may come across of a need to register beans conditionally.

Using Spring Boot on OpenShift. Spring Boot is certainly an interesting framework for the development of microservices and other lightweight Java based applications. I spent some time recently working with a plethora of Java microframeworks to determine which one I would like to use for some personal projects that I have been working on. Namely, I have tried out spark, WildFly Swarm, and Spring Boot. This post is not to declare which one I like the best as that isn’t really relevant to why you are probably reading this post and depends greatly on the specific project. I am not from the one framework to rule them all camp but more of use the right framework for the job.

Single Page Angularjs application with Spring Boot and Yeoman. I am very thankful for tools like yeoman which provide a very quick way to combine different javascript libraries together into a coherent application. Yeoman provides the UI tier, if you needed to develop the services tier and a web layer for the static assets a good way to package it is to use Spring Boot. I know there are tools like JHipster which make this easy but if you are just looking just a basic template what I am outlining here should just suffice.
